Fixed Cone Valves

Learn about our Fixed Cone Valves

Known for its excellent energy dissipation, the Fixed Cone Valve is a regulating discharge valve for outlet works on medium to high head dams. This valve features a conical head that extends beyond the end of a cylindrical body. Radial ribs support the cone and the opening that is controlled by a sliding gate sleeve. The gate sleeve slides over the valve body and opening to control flowrate and fully close against the cone. As the valve opens the flow is dispersed into the atmosphere in an expanding cone shape that aerates and disperses energy. The valve can be operated by electric screw stems or hydraulic cylinders. For outlets that required a contained spray, a discharge hood can be included. Steel-Fab uses a conservative design focused on minimized vibration and extending valve life. Fixed Cone Valves are also referred to as Howell Bunger valve.
